I recently purchased a new CVA muzzleloader. I elected to shoot the bh 209 so I purchased the 209 breach plug. After sighting it in I found the primers aren't sealing and I'm getting a lot of fouling behind the primer pocket. I'm using cci 209 magnums. Any recommendations on how to resolve this issue?

I Use O-Ring on My ACCURA II!
Back Me Off to 1,700 Yards,650 is a Little Close & I'm Not Comfortable with it!
A GUT SHOT at 1,700 Yards will Still Make Some Good BRAGGIN Rights so I Can Say I At Least Hit Him!

Winchester 209 primers seal the best as they have the widest dimensions. Also what Bobcat said, use a rubber o-ring in the primer pocket. That will eliminate blow-back. Also you want to make sure and keep the flame channel clean on your breech plug.
I just traded for a Winchester Apex(same as cva kodiak) on this forum a week or two ago. I had it out this week and it wouldn't ignite the powder at all. After tearing it completely apart, polishing the firing pin, chamfering and polishing the firing pin hole, checking springs, sear and everything else, I took it back out and same problem. I swapped in a new breech plug and bang!
All my CVA muzzys had serious blowback and occasional misfires until I started using Win 209 primers and using o-rings. Not a problem since I've done those things. Check out modern muzzleloader forums for more info. There is a chart for primer dimensions which is also helpful. Some people use stainless steel washers for a shim instead of o-rings.
The o-rings I'm using are 1/4 x 1/8 x 1/16 part# 780003 Faucet 1-1a; I think they are a Hillman product but I'm not sure. I just happened to have a package of them in my wallet so I can get more when I'm at the hardware store.
Good luck and let us know how it goes.

Doesn't matter what primer you use, they will all be dirty in that action due to the loose tolerance they allow.
You can either 1: install a firing pin bushing shim kit, or go the easy route and install an O ring into the primer pocket.
